Trina Disses Khloe Kardashian: James Harden 'Sloppy Seconds,' French Montana Cheating Scandal?

Rumors suggest that Khloe Kardashian recently hooked-up with Houston Rockets superstar, James Harden. The NBA baller's ex-girlfriend Trina isn't jealous - although she's definitely not amused, either!

But the "Keeping Up With The Kardashians" starlet can have "Da Baddest B*tch" emcee's leftovers all she wants:

@TRINArockstarr: "Sloppy seconds..."

Ouch.

According to the popular gossip webloid The Daily Beast (via bossip.com), Kardashian and the 25-year-old All-Star were spotted partying together in Las Vegas over the holiday weekend. They danced along to DJ Zedd at the infamous Encore Beach Club, and looked very much like a couple. Several other big-name celebrities also attended the bash, including "Dancing With The Stars" winner Rumer Willis, former basketball player Rick Fox, rap producer Jermaine Dupri, and remix mastermind Deadmau5.

Funny enough, Trina was also in Sin City celebrating Independence Day. Will a heated confrontation take place soon?

Does this mean Lamar Odom's ex is no longer with rapper French Montana? Ha - the "Like This" songstress once dating him, too!

In fact, she used to hang with older sis Kim Kardashian back in the day. Here they are showing off their bootylicious curves back in 2010 (before Kanye West entered the picture):

Another amusing sidenote - Wiz Khalifa's ex-baby mama Amber Rose was one romantically involved with Harden. Yes - Kardashian's ultimate "frenemy." Hollywood's a small world when it comes to dating!

Meanwhile, Khloe continues ignoring such "cheating scandal" shade on Instagram, and instead flaunts her sexy weight loss body transformation:

khloekardashian: "Slight work."

So far, the Maybach Music Group hypeman remains mum on social media. Maybe Kardashian just likes playing the court! Get it? Well, Twitter fans are now abuzz:

@ThatDudeMCFLY: "James Harden was dating Trina? And Now Khloe Kardashian? #fearthebeard."

@jon_bois: "just saw james harden is dating khloe kardashian! hope they have a good time, they seem like decent folks."

@Tweetingnflnba: "James Harden is dating Khloe Kardashian? Beware Rockets fans, look at what happened to Lamar Odom..."

So, are Kardashian and Montana officially over for good?
